` IMPROVEMENTIN PLASTIC JACKET AND CONDENSERFOR CARBURETERS.

Specification forming part of Letters Patent No. 198,150, dated December 11, 1877; application filed f December 1, 1877.

To'all lwhom t may concern:

Be it known that I, ALONZO W. PORTER, of New York, in the county of New York and State of New York, have invented a new and valuable Improvement in Plastic Jacket and Condenser; and-I do hereby declare that the following is a full, clear, and exact description of the construction and VOperation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon. i

Figurel of the drawings is a representation of a central vertical section of my plastic jacket and x condenser, and Fig. 2 is a plan wa'ew of the same. Fig. 3 is a side elevation thereof, and Fig. 4 is a detail sectional view.

This invention relates to details in the construction of that class -of machines used for carbureting air and gas for illuminating purposes, the object being twofoldrst, to maintain an-equabletemperature of the water in the outer case or jacket surrounding the carbureting -compartments andy the fountain or holder of hydrocarbon spirits against the encroachment of the temperature of the surrounding air; secondly, to provide a meansv for condensing all excess of vapor from the gas or air when carbureted. i

My invention, then, consists, first, in applying to the outer casing or jacket of a carbureter or gas-machine a non-corrosive coating of asphalt or other non-corrosive substance, and covering the same with a non-conducting plastic over-jacket.

It also consists in the peculiar construction and application of a condenser for condensing out of the air or gas any excess of vapor which may be temporarily mixed therewith in consequence of too high a temperature or too light gravity of the common spirits used in themachine.

In the accompanying drawings, A represents a carbureting-vessel, which may be provided with any preferred kind of compartments, also with a compartment for containing the hydrocarbon spirits, with suitable inlet and outlet passages for air or gas into and to the burners, and preferably surrounded by a jacket, B, containing water, to be kept at a uniform temperature by means of a hydrothermostat regulator.

I nd in practice that any attempt to maintain a uniform temperature of the carbureter, so arranged or otherwise, is seriously and fatally interfered with by the surrounding air during those periods in which the machine may be at'rest, owing to the contents of the vessel orcarbureter becoming equalized with the temperature of the external air, thereby raising the temperature of the hydrocarbon spirits in the machine too high, and causing too rapid evaporation of the hydrocarbon spirits, supercharging the air or gas with the vapor of the spirits, causing two bad effectsto wit, smoke and precipitation of the excess in the distributing-pipes of the building'.

These phenomena are of short duration, and generally confined to the first thirty minutes of the working of the machine; yet the result is damaging, and may be dangerous, and in practice must be avoided. Owing to the coldness of the water-jacket, caused by rapid evaporation of the hydrocarbon spirits in the carbureter, this outer case or jacket is liable to condense the moisture in the surrounding air, which will collect upon the surface of the jacket, thereby causing oxidization of the metal. forming the outer jacket. This damaging result is increased by the application of a plastic jacket to the metal Lmless it be provided against.

To prevent these evil results, I prepare the outer surface of the jacket B with a coating of asphalt or other non-corrosive coating, to prevent the oxidization ofthe metal above referred to. Over this coating I place or apply a thick over-jacket of plastic non-conducting material, which may begypsnm, kaolin, and

hair, or any other suitable non-conducting material, to keep out the heat of the surrounding air, thereby enabling me to secure a more equable temperature for the contents of the machine in overheated rooms, and in different climates and seasons.

Also, as above stated, I iind in practice that in excessive charging of the air or gas with the vapors of the hydrocarbon spirits, caused by too high temperature or too light gravity of the spirits, and passing the gas, when so charged, into distributing-pipes, which may be many degrees colder than the point at which the carbureting is effected, precipitation of the excess or condensation takes place in the distributing-pipes. This it is necessary in practice to guard against absolutely. To accomplish this I have placed between the carbureter and the riser 7 a box or compartment, D, which I call an atmospheric condenser.77 In this box is placed a series of horizontal attened folds, E, with intermediate passages between them for the circulation of air between and around the folds. At one end of the folds 'is attached a pipe, F, through which the gas Xed a large pipe, H, communicating with the outdoor air, and is provided with a cut-off, a, to open and close the communication.

To the upper part of the rear end of the condenser-case is an outlet pipe or flue, I, which is also provided with a-cut-off, b. The latter pipe, I, may also communicate with the outer air, or with the compartment air in which the machine is placed. In this ue I is arranged av gas-burner, which is supplied by means of the small gas-pipe c, having regulating-cock d. The burner is lighted through the aperture c, covered by a slide, j'.

The object of iiattening the folds is to gain greater condensing-surface for the gas within a small space. A coil of pipe or sinuous passages maybe substituted for the folds when desired.

A space, M, is left above the folds in the box D, (sce Fig. l of the drawings,) to receive ice or any freezing-mixture, if it should be desirable.

'Ihe letter O designates a hinged cover or lid to the box, and may be provided with a lock and key. In case ice should ever be used to reducev the ltemperature of the folds, the drainage of the melting ice is discharged by the waste-water pipe h.

In operation, the hydrocarbon spirits are poured through the filling-pipe K into any suitable holder. The gas passes through an inlet-pipe (not shown) into the carburetingchambers, and passes over the hydrocarbon spirits contained therein, and takes up the vapors thereof by any of the known processes.

The gas, after being carbureted, passes out of the carburetin g-chambers into the condensingfolds, where the excess of hydrocarbon fluid` outdoor air, and as no distributing-pipe can` be colder than the outdoor air, it necessarily follows that'the gas passing through the folds can find no colder place beyond the condenser; consequently no further precipitation can take place in the distributing-pipes.

By means of this atmospheric condenser, so arranged, or its equivalent devices, and the plastic over-j acket hereinbefore described, I am enabled, in practice, to secure a more uniform and satisfactory result, with greater economy and safety in the manufacture of air-gas for country dwellings and buildings, and in the carbureting of street-gas for illuminating purposes than has heretofore been obtained by devices of which I have any knowledge.

Having thus described my invention, what I claim as new,'and desire to secure by Letters Patent, is

1. In combinationvwith a carbureter, a surrounding case or jacket having its outer surface covered with a non-corrosive coating, and
